Hi,
welcome to Aptosid. The official sources can be found at http://aptosid.com/files/misc/ and are sufficient for almost all needs.
The smxi script is not supportable by us, and we strongly recommend to stay away from it.
Greetings,
Chris

Edit : Well it seems debian multimedia repositories are censored here. Seems a bit odd as I'm pretty sure it doesn't present any legal issues in Europe and many other countries.
They are quite easy to find though if you search for them.

That multimedia is forbidden here is written down in your rules you have accepted while registering.
For details consult google about the the Digital Millennium Copyright Act which has equivalents in more or less all countries around the globe. (if the explanation in the **removed** link is not enough already…)

The problem is that these laws forbid breaking copyprotections on e.g. DVDs (which you need to play some)- but most countries haven't decided (by a lawsuit at the highest instance) if the used protection is valid or not. The only exception i know of is Finland, but this one has properly other 'nice' rules…

And with my 'APT hat' on i strongly advice against setting APT::Default-Release to 'stable' in an 'unstable' as this will have many interesting results, but most likely not always these a user might expect…

AFAIK software patents are still not valid in Europe, even though it's possible to register them. I'm aware about the USA trying to impose their DCMA all over the planet, haven't read anything these last years suggesting they had effectively managed to get anywhere near having most of the countries adopting those rules. Copy protections can still be circumvented without any issue as they fall under the copyright exception of copy for personal use in many countries. If you want to add another country to your list, Belgium, here personal use copy and "pirate" P2P is implicitly condoned by the copyright taxes we pay on writeable CD's, DVD's, Hard drives and other media.

If you have any sources of information confirming your claims about DCMA being adopted and enforced almost everywhere I'd be happy to enlighten myself.

Thanks for pointing out my error there about the APT::Default-Release, I checked my system just to be sure and it was set to sid as it should.

This site is hosted in Germany and that country has pretty strong copyright laws too and the aptosid team has to enforce the restrictions on everyone...otherwise the site could be shut down for copyright reasons

The obvious solution in this case would be to host it in a country which doesn't have these restrictions, as many controversial websites have done in the past. Am I missing something here?

The issue at hand here is the ability to use a computer to it's full potential. That doesn't seem wrong in any aspect. Downloading copyrighted material for free seems much more questionable yet it still makes up a considerable chunk of all internet traffic, with many websites enabling it being hosted in countries which do have those restrictive laws.
If linux users weren't able to use commonly available multimedia formats and media, how many of them would stop seeing it as a viable platform?
This is something worth fighting for, not just accept as an unavoidable fact.

Our policy is clear and necessary to protect our team, and users in several countries as well. This forum is definitely the wrong place to fight for political changes - not here, please. Please stick to support questions.

The OT has rendered his system unsupportable and should seek support from the author of the script he uses. Thanks for understanding.
